Last week, Hannah was kidnapped and taken to Idaho by family friend James Lee DiMaggio, who is believed to have killed her 44-year-old mother Christina Anderson and 8-year-old brother Ethan.

Anderson was reunited with her father on Sunday after search crews spotted her and the 40-year-old DiMaggio in an Idaho wilderness area Saturday afternoon and fatally shot him.

In one response on Ask.fm, the account holder shows off a photo of her newly painted nails. The poster also said DiMaggio tricked her family into visiting his home earlier this month.

"He told us he was losing his house because of money issues so we went up there one last time to support him, and to have fun riding go karts up there but he tricked us," the account holder wrote.

The account holder also said DiMaggio tied up her brother and mother in the garage before driving away with her to Idaho.

The account holder confirmed she did not know that her brother and mother had died until after she was rescued and said DiMaggio rigged his house to catch fire after he and she left. Authorities responded to the fire and discovered the bodies Aug. 4.

Asked why she thought DiMaggio did what he did, the account holder responded, "Because he's a psycho." The poster also wrote that she hopes the dead murder and kidnapping suspect "burns in hell."

Investigators were led to Idaho after DiMaggio and Hannah were spotted in the wilderness by a group of horseback riders. The account holder wrote on the website that she tried to be calm when they encountered the group.

"I didn't want them to get hurt. I was scared that he would kill them," the poster wrote.

The account holder wrote that she suffered only a twisted knee in the ordeal and that she didn't try to run away because "he would have killed me."

Asked if DiMaggio had a crush on her, the poster wrote, "Yes he did. He said it was more of a family crush like he had feelings as in he wanted nothing bad to happen to me."

The account holder noted, however, that DiMaggio "had a gun and threatened to kill me and anyone who tried to help."

Hannah's family has yet to confirm the authenticity of the postings. San Diego County Sheriff's Department public information officer Jan Caldwell said the department was aware of Hannah's online posts, but "we won't be making any comments" about them.

The Ask.fm account, which 10News learned was created well before she was abducted, was taken down early Wednesday morning.

In one photo posted Tuesday, a caption likely referring to her mother Christina Anderson and her younger brother Ethan read: "You both didn't deserve any of this. And I'm sorry I couldn't have saved you."

Behavior analysis expert Michael Mantell told 10News the comments posted on the pages are normal for someone who just went through a traumatic experience.

Mantell said allowing her to voice her feelings on the Internet is a form of therapy for her -- a part of healing that he believes shouldn't be shut down.

"It's like putting tape over someone's mouth," Mantell said.

In a bizarre twist, DiMaggio died exactly 15 years after his father committed suicide. DiMaggio's father had a history of substance abuse and criminal offenses. In 1988, the elder DiMaggio, also named James, kidnapped an ex-girlfriend's then 16-year-old daughter. The elder DiMaggio's victim, now an adult, recently told a local TV station that her attacker professed his love for her and said he was taking her to give her a good life.
